D(r)=(27(r)+13)/(26)

D (r) = \frac{27 ( r ) + 13}{26}

r = \frac{13}{26 D - 27}; D \neq = \frac{27}{26}

Solution steps

D (r) = \frac{27 ( r ) + 13}{26}

Multiply both sides by

26

26 Dr = 27 r + 13

Move

27 r

to the left side

26 Dr - 27 r = 13

Factor

26 Dr - 27 r : r (26 D - 27)

r (26 D - 27) = 13

Divide both sides by

26 D - 27; D \neq = \frac{27}{26}

r = \frac{13}{26 D - 27}; D \neq = \frac{27}{26}
